Sony Alpha NEX-3 Advanced Camera, $440

Sony's interchangeable-lens cameras, the Alpha NEX-3 and NEX-5, made quite a splash when they launched last year. They're thin and light, have 14.6-megapixel sensors--and just like DSLRS, you can swap lenses. Read our hands-on for details. The Sony Alpha NEX-3 sold at $550 with a basic lens kit last year, but now the price has dropped. Dell Home has the NEX-3 on sale right now for only $440, and shipping is free.
